SP-540v - light overspray, followed by mis-printing horizontal & bi-directional head test boxes - MyVersacamm.com2019-05-25T13:09:48Zhttp://myversacamm.com/forum/topics/sp-540v-light-overspray-followed-by-mis-printing-horizontal-bi?commentId=826732%3AComment%3A182513&xg_source=activity&feed=yes&xn_auth=noI just did another bi-directi…tag:myversacamm.com,2018-01-09:826732:Comment:1825292018-01-09T20:09:04.670ZBrennan Phttp://myversacamm.com/profile/BrennanP

<p>No1 &amp; No2 were at +10 and I should have had them more around 0.</p>
<p>Same with 3 and 4. <br/>So I guess the service menu sets the baseline back to 0, and the regular menu let's you fine tune this?<br/>Correct me if I'm wrong here.</p>
<p></p>
<p>Is this also the case with the print-cut adjustment? Set it in service menu and fine tune in regular menu if required? I much prefer to use the three square method for correction in the service menu, as it gives me more precise results than the single vertical and horizontal cut test.</p>
<p></p>
<p>Sorry for the re-write of some of the same questions over, but I'm thinking out loud here, and hopefully this helps some other folks down the road as well.</p> "Like Irv said, do the bidire…tag:myversacamm.com,2018-01-09:826732:Comment:1826112018-01-09T08:43:56.876ZBrennan Phttp://myversacamm.com/profile/BrennanP

<p>To clarify, I have been doing the bi-directional in service mode. </p>
<p>Have a look at <a href="http://myversacamm.com/forum/attachment/download?id=826732%3AUploadedFile%3A182501"><img src="http://static.ning.com/socialnetworkmain/widgets/forum/gfx/fileicons/jpg.gif?xn_version=1805699943" alt="20180107_183003.jpg"/></a><span> </span><a href="http://myversacamm.com/forum/attachment/download?id=826732%3AUploadedFile%3A182501">20180107_183003.jpg</a> above. </p>
<p>It's a bit tough to see, but I need to resolve the reason for the skewed orange and blue lines. <br/>They should appear more vertical like the 2nd row down. I realize that I am to adjust my panel to the values I see best aligning, but they're pretty skewed and at times I can jump over 3-4 boxes and the alignment is enough that I'm not positive on which area to look at. </p>
<p></p>
<p>If you look specifically at Row 1:<br/>-1, 0, +1, you will see that the bars are not vertical but randomly on skewed angles. <br/>This makes it very difficult to view alignment. In past months it was never like this. <br/><br/>To add:<br/>Printing and samples are done with the low head height. <br/><br/>Thanks again gents for your help. <br/>Means a lot :)</p> "better to see a VW test prin…tag:myversacamm.com,2018-01-09:826732:Comment:1823942018-01-09T08:41:08.836ZBrennan Phttp://myversacamm.com/profile/BrennanP

I'm not positive that static was the issue at the moment based on the below findings.<br/>I'll double-check the bi-directional settings in both service mode and regular. Out of curiosity, once it is done in service mode, what is the reason for following in regular?<br/><br/>My design essentially consisted of black, grey and a blue/green color. </p>
<p></p>
<p>I had initially had the black as CMYK 0,0,0,100, Green as a Pantone, and Grey as a CMYK.</p>
<p>I typically prefer to use 50,50,50,100 for black, but was getting even muddier overspray. <br/>I do realize many on here swear to use RGB color only, but I am mostly familiar with CMYK and prior to this wasn't having much issue. So yes, the overspray is still an issue if I'm trying CMYK combinations.<br/> <br/>Even though the black should have just been firing at 100 on the K channel, I have reason to believe the Versaworks RIP still converted it to some sort of multi-CMYK, hence some of the overspray.</p>
<p></p>
<p>Fast forward Black was done with Roland BK21A, Green as Pantone, Grey as CMYK.<br/>It looks great and the black is crisp. Pretty odd since BK21A in Corel Draw shows as 0,0,0,100.</p>
<p></p>
<p>I even did a sample with three tones of black, 0,0,0,100, Roland Black, and RGB black. The only one that came out crisp was the Roland Spot colour once again.<br/><br/></p>
<p>In Versaworks this whole time I've had Spot colors set to convert in the second tab. <br/>Anyhow that change with the black made every thing crisp.</p> Pictures can always misrepres…tag:myversacamm.com,2018-01-08:826732:Comment:1825132018-01-08T03:04:21.574Zirving donaldsonhttp://myversacamm.com/profile/irvingdonaldson
<p>Pictures can always misrepresent what is actually there.</p>
<p>So check humidity - static is a possibility and the machine will let you know when it is too cold to print.</p>
<p>Check your bias, it looks off which can give you what you see and vertical and horizontal.</p>
<p>Do your bi default in service</p>
<p>Then do it in user mode.</p>
<p>Your nozzle test shows that you should have clear prints</p>
